Ferulic acid (FA) is a dietary phytochemical that acts as an antioxidant and possesses various other health-promoting properties.
Understanding Ferulic Acid
Ferulic acid is a ubiquitous plant constituent. It's derived from the metabolism of phenylalanine and tyrosine. It's found in high concentrations in plant cell walls, particularly in bran fractions of grains like rice, wheat, and oats. Chemically, it's an organic compound belonging to the hydroxycinnamic acid family.
Key Properties and Functions:
